Energy Efficiency in Telecom Italia (2/2) Environmental sustainability initiatives 4 Telecom Italia contributions in: 4 Development of the new version of the EC Code of Conduct on Energy Consumption of Broadband Communication Equipment (BB Co. C V 5) 4 ITU-T’s “green” standards (Recommendations L. 1002, L. 1340 and L. 1010) 4 “New sustainability model for the TLC/ICT sector” agreement (May 21 st, 2012) 4 Signed between Telecom Italia and the Italian Environment Ministry 4 Commitment in buying electricity from renewable sources only 4 Guarantees of Origin ensuring the use of renewable sources only Telecom Italia S. p. A. is 100% powered by renewable energy 4 Further reduction of the environmental impact of Telecom Italia’s activities (-70 % CO 2 emission) 4 Smart Center 4 Telecom Italia is the 2 nd largest user of electric power in Italy (2. 2 TWh/year) 4 Country-level monitoring of the energy consumption of the infrastructure (radio base stations, data centers, offices, shops and laboratories) 4 Telecom Italia Green networking and renewable energy sources Damiano Rapone – Engineering&TILab, Wireless Access Innovation dept. 7

The importance of Green ICT (1/2) 4 Currently 3% of the world’s annual energy consumption is related to Information and Communication Technology (ICT) infrastructures 4 Mobile communication systems represent ~ 15% of total ICT sector 4 ~ 10% of ICT’s energy consumption can be attributed to mobile systems ICT’s energy consumption rises at ~ 15 -20% per year 4 ICT is thus a quickly-growing contributor to CO 2 emissions 4 ~ 2% of the worldwide CO 2 emissions (comparable to airplanes, ~ 25% of cars’ emissions) 4 Within ICT, mobile communication systems contribute ~ 12% in CO 2 emissions 4 Expected to grow by nearly a factor of 3 in 2020 (with respect to 2002 emissions) Green networking and renewable energy sources Damiano Rapone – Engineering&TILab, Wireless Access Innovation dept. 8

The importance of Green ICT 4 Mobile network’s energy consumption grows rapidly because of the dramatic mobile data traffic increase (2/2) 4 Thepriceofelectricityiscontinuously increasing (+10% annually in European Union) 4 This affects the operators’ OPerational EXpenditures (OPEX) Reducing energy consumption not only a matter of being green and responsible but also economically sustainable Green networking and renewable energy sources Damiano Rapone – Engineering&TILab, Wireless Access Innovation dept. 9

Mobile networks and renewable energy sources: a possible synergy 4 Improve the Energy Efficiency (EE) in all components of the mobile network The key source of energy consumption is the operation of base stations (60 -80% of the network’s total energy consumption) 4 Replacing traditional power sources with renewable “green” solutions not only benefits the environment but also positively impacts operator’s OPEX 4 Green energy saves on-grid power consumption 4 Green power generation dependent on the power generators’ geo-locations and weather conditions 4 Excess electricity sold to the electrical grid 4 Higher cost-per-watt of renewable sources (if connected) 4 Diesel-powered generators no more needed (in on-grid sites) 4 Additional CApital EXpenditures (CAPEX) due to power generation infrastructure and batteries 4 Base station located away from electrical grid 4 Backup batteries to maintain the base station active when green energy is not sufficient 4 System still works if electrical grid is off Green networking and renewable energy sources Damiano Rapone – Engineering&TILab, Wireless Access Innovation dept. 10

Conclusions 4 ICT’s energy consumption rises at ~ 15 -20% per year 4 Both increasing electricity price and foreseen traffic data growth negatively impacts operator’s OPEX 4 Reducing network’s energy consumption for economic and environmental sustainability renewable energy sources 4 Improving the Radio Access Network infrastructure (i. e. , base stations) Energy Efficiency is the key to Green ICT Green networking and renewable energy sources Damiano Rapone – Engineering&TILab, Wireless Access Innovation dept. 11

Mobile Energy Efficiency (1/2) 4 In mobile communication networks a large part of the carbon footprint stems from electricity consumption during operation and manufacturing (2007) 4 Most of the today’s power consumption comes from the RAN: 4 high number of sites 4 high and not scalable base station consumptions Green networking and renewable energy sources Damiano Rapone – Engineering&TILab, Wireless Access Innovation dept. 14

Mobile Energy Efficiency (2/2) 4 Radio access network energy consumption is a considerable portion of the entire energy consumption of the mobile network, both considering already deployed network but also growth forecasts due to the increasing mobile ultrabroadband traffic demand 4 Areas of potential improvements: at component / node level: 4 Hardware (HW) improvements can give in a first stage the most of the gains; in general each new HW generation is typically more energy efficient but will reside unchanged in the network for several years at system and network level: 4 New functions, network management mechanisms and RRM algorithms, features typically implemented in SW; potentially can be upgraded and introduced in the network over the lifetime of several HW generations.

The simple truth about mobile Energy Efficiency… 4 Up to now conventional design of Mobile Networks is performed by considering full load (maximization of the capacity of the nodes; performances traditionally evaluated in terms of spectral efficiency) 4 But in practical situations the problem is that: 1. most of the time the network is not loaded 2. in that period base stations still consume a lot ed ad t as c lo w i is aff y r rg w t e en f lo h c so u M ime t in Source: EARTH D 2. 3 deliverable.
